| hib vaccine coverage in children attending day care/nursery school in east york. | this survey assessed haemophilus influenzae b vaccine coverage and factors affecting compliance in children at increased risk. a telephone survey was conducted of a random sample of 75 children, aged 24-60 months, attending licensed day care/nursery schools in east york. 96% of the sample was surveyed; only 51% were vaccinated. older children were less likely to be immunized and there were more single-parent families among the non-vaccinated. the age, educational level and country of birth of th ... | 1990 | 2331655 |
| antibiotic susceptibility of blood and cerebrospinal fluid isolates of haemophilus influenzae. | one hundred and sixty-nine blood and cerebrospinal fluid isolates of haemophilus influenzae, collected in the province of ontario from children and adults from 1976 to 1983, were tested for susceptibility to six conventional and eight newer antibacterial drugs. most active were ceftriaxone, ceftizoxime and cefotaxime (mic90 less than or equal to 0.02 mg/l); latamoxef (moxalactam), acrosoxacin and ceftazidime were close behind with mic90s in the 0.05-0.09 mg/l range. twenty-five strains (14.8%) w ... | 1985 | 3872296 |
